If aggregate planned expenditures equal real GDP, then
A) inventories increase above their planned levels and businesses decrease their production.
B) inventories decrease below their planned levels and businesses increase their production.
C) there is no equilibrium level of real GDP.
D) inventories decrease below their planned levels and businesses decrease their production.
E) unplanned inventory changes equal zero.
The correct answer and explanation is :
The correct answer is:
E) unplanned inventory changes equal zero.
Explanation:
In macroeconomics, the concept of equilibrium GDP occurs when aggregate planned expenditures (or total spending in the economy) match the actual output produced, which is represented by the real GDP. Aggregate planned expenditures are the sum of consumption, investment, government spending, and net exports (exports minus imports). The real GDP reflects the total value of goods and services produced in the economy.
When aggregate planned expenditures equal real GDP, the amount of output produced in the economy matches the amount of output that businesses and households planned to purchase. This situation indicates that there are no unexpected changes in inventories, meaning that what businesses expected to sell aligns perfectly with what they actually sold.
Here’s why answer E is correct:
- When businesses produce goods and services, they anticipate a certain level of sales based on their expectations about consumer behavior, investment, and government spending. If their sales match expectations, there will be no change in their inventory levels beyond what was planned.
- In this scenario, unplanned inventory changes are zero, as businesses are neither overproducing (which would lead to an accumulation of unsold goods) nor underproducing (which would lead to a shortage of goods to meet demand).
- Unplanned changes in inventory occur when actual sales are either higher or lower than expected. A balance between planned expenditures and real GDP ensures that businesses’ expectations are fully realized, meaning there are no unplanned changes in inventory levels.
To summarize, when aggregate planned expenditures equal real GDP, the economy is in equilibrium, and there are no unintended changes in inventories. This reflects the correct operation of supply and demand in the goods market, with businesses neither overproducing nor underproducing.
